To ALL WHoM rr MAY ooNoERN:

Be it known that I, WILLIAM NELSON, of Cacher-ville, in the county ofYole, and State of California, have invented a' new and improvedGang-Plough; a-nd I do hereby declare that the following is afull,clear, and

exact description thereof, which will enable those skilled in the art tomake and use the same, reference being had to the accompanyingdrawings,.i`orming part of this specification.

This invention relates, rst, toeJ new and improved application ofthoplough-beams, whereby the ploughs may, with the greatest facility, beraised entirely out of the ground when necessary,'as, for instance, inturning the machine at the endsof fui-rows, moving it from place toplace, if-c., 85e., and the ploughs at the same time renderedA capableof being rmly secured vin position, so as to plough at any requireddepth, and also adjustedy ata greater or less distance apart, ascircumstances may require. In the accompanying sheet of drawingsrVFigure-1 is aside sectional view ofmy invention, taken inthe line xrrr, fig. 2. Figure 2, a front view of the samer A Figure 3, ahorizontal section of the same, taken in the line a" x', g. 2. Figure 4,a section 'of a portion of the same, taken in the line y y, iig. 2.Figure 5, a section of a portion of the same, taken in the line z z,iig. 2. Similar letters of reference indicate corresponding parts. Arepresents an axle, having a ywheel,-B, fitted loosely on cach end ofit, aad C represents a frame, to

which the draught-pole D is secured. The rear end of the frame C is ttedloosely on the axle A, so that the Vlatter may turn freely in the frame.To the rear part of the frame `C there is attached an upright frame, E,

on which the driver-s seat F is placed.

G is a segment or curved bar, the upper end of which is secured to theupper part of frame E, and the lower end secured to the rear or innerend of the draught-pole D. This bar G is notched at one edge or side toreceive a lever, H, the lower end of which is pivoted to the inner partof the draught-pole within the frame vC, as shown by the dotted lines inlig. 1, at ct. This lever H is connected by a. chain, I, with theu'pperend of a lever or arm, J, the lower end of which is firmly connected tothe axle A by va clamp, K, as shown clearly in fig'. 4, I

, L L represent two boxes which are composed each of an upper and lowerplate, b b, connected together at a` suitable distance apart by sideplates a c, through which the axle A passes, the upper and lower platesb b being secured by bolts d to the side plates c c. Through these boxesa horizontal shaft, M, passes, on which4 the front ends of plough-beamsN N are fitted loosely,

The boxes L L may be adjusted laterally on the axle A, and secured atany desired point, so as to admit ot the beams N, and consequently theploughs, being placed at a greater or less distance apart. ascircumstances may require.

The lower plates b ofthe boxes extend back considerably beyond thelatter, and have upright yokes or frames 0 secured to them, throughwhich yokcs the ploughbeams N N pass. In the lower parts of these yokesorframcs there are placed wooden blocks e, one in ett/.111,071 which theplough-beams rest, and when no lateral adjustment of the ploughs isrequired-the beams may bc clamped down on these blocks by screwsf, whichare fitted in the upper ends of the yokes. When the screws are notscrewed down on the beams the latter are allowed a certain degree ofplay in the yokes, so that the plonghs may work towards or from eachother, to clear or a'void obstructions.

4When necessary or desired, the ploughs may be raised entirely out ofthe ground by actuating the lever il, which, owing to its connectionwith the axle A, as shown, causes the axle toturn, and thereby elevatethe rear ends of the beams N N, and consequently the ploughs and bysecuring the lever H in different upper Anotches in thesegmenti-bar.G,-the ploughs may beadjustcdto penetrate` the earth` at agreater or less-depth,A

as may be required.

The lever H is held in the notches oi` the bar 'G by means of a curvedrod, P, the lower end of which is pvoted on the front part of frame C,and has its upper end fitted between a pin, g, on the top of frame'E andthe side of the drivers seat F. This rod P keeps the lever H engagedwith the toothed segment or bar G.

The ploughs Q are attached to the rear ends of the beams N in the usualor in any proper manner.

I claim as new, and desire to secure by Letters Patent- 1. The attachingofthe plough-beams N N to the axle A by means ofthe boxes L L,constructed substantially as shown, in combination with the frame C, towhich the draught-pole D is attached, said frame being connected to theaxle A, as shown, and all arranged to operate in the mannersubstantially as and for the purpose set forth. v v

2. The notched segment-bar G, in combination with the lever H and arm J,connected by the chain I, and attached respectively to the draught-poleD and the axle A, and all arranged to operate in the mannersubstantially as and for the purpose specified.

3. The yokes or frames O, provided with the serewsf, and attached to thelower plates b ofthe boxes L L with the plough-beams N passinr throughthem, substantially as and for the purpose set forth.
